I'm limited to SATA II on my P5K-premium-WIfI/AP, but just because IOPs (coming from a HDD)...Can't say how happy I am I!!!. I'll write back once this little sh!t gets dirty and/or wears out. Fedora 26/Ubuntu beta 17.10 (yes, swap partition{shared}) , and kvm/qemu win/lin machines on it!
Boot times (from HDD) are 100:1 and vm's response times close to 20:1! (!!!)
